The World's Oldest Profession

OK, Not really. This is a poll about the world's second oldest profession. I was researching another topic on the internet for my job, and my work led me to type in "World's Second Oldest Profession" into my search engine. I didn't know there was a "world's second oldest profession", (nor did I really care) but what I did find out is that there are 34 contenders vying for the #2 position.

Which profession has earned and deserves the title of "World's Secnond Oldest Profession"?
